Application filed. June 7, 1921.

To all whom it may concern:

Be it known that we, ABRAHAM LEVINE and Louis Orrnnnnn, citizens ofRussia, and residents, respectively, of the city of New York, borough ofBrooklyn, in the county of Kings and State of New York, and of the cityof New York, borough of Bronx, in the county of Bronx and State of NewYorr, have invented a new and Improved Attaching Means forSeparableFastener Elements, of which the following is a full, clear, andexact description.

This invention relates to improvements in means for attaching separablefastener elements to flexible supports, particularly to a novel meansfor attaching a hasp to the flap of a brief case, pocket book, musicroll, or similar container.

It is customary to rivet these hasp members to the flap of a brief easeor the like, and the primary object of this invention is to provide ahasp, which carries its own attaching means, which may be quickly andeasily attached, and which will be a time and labor saving device.

A further object is to provide a hasp member of this character, whichwill be simple and practical in construction, durable and efficient inuse, neat and attractive in appearance, and comparatively inexpensive tomanufacture.

lVith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claim. V

In the accompanying drawings Figure 1 is a perspective view of anunattached hasp member embodying our invention; and

F 2 is a view in longitudinal section through the flap of a brief case,illustrating the hasp in applied position.

Referring in detail to the drawings, we have illustrated one element ofa separable fastener, which comprises a sheet of matespecification ofLetters Patent.

rial 5, bent along longitudinal lines until it is substantiallyii-shaped in cross section. A hasp 6, engageable with the otherseparable fastener element (not shown) is rigidly attached to one outerface of the plate.

One free edge of the plate 5 carries a plurality of integral prongs orspurs 7, and the other free edge of the plate is beveled or rounded, asindicated at 8.

In attaching the plate to a support, such as the flap of a brief case orsimilar article, the edge of the flap designated by the referencenumeral 9. is inserted between the opposite sides of the plate 5. Thefree edges of the plate are then forced toward each other by a suitabletool, the spurs 7 piercing the fabric of the flap 9, and when they comein contact with the beveled cam surface 8 being upset, as indicated inFig. 2, so that they firmly grasp the fabric.

It is to be understood that we do not claim as novel the particularshape of the hasp member shown, but claim rather the specific means forattaching any conventional form of hasp member to a flexible support.

Various slight changes and alterations might be made in the general formand arrangement of the parts described without departing from theinvention and hence we do not wish to limit ourselves to the precisedetails set forth, but shall consider ourselves at liberty to make suchslight changes and alterations as fairly fall within the spirit andscope of the appended claim.

We claim:

A separable fastener element including a plate, bent along longitudinallines into substantially rt-shape, spurs carried by one edge of theplate, said plate being bent longitudinally adjacent its other edge toprovide a cam surface, said surface being engageable with the spurs toupset the same when the edges of the plate are advanced toward oneanother.
